Alien planets are far away but extreme lasers on Earth are giving scientists a way to investigate what they're like.

By applying machine learning to vast TESS datasets, researchers have built one of the most precise catalogs of nearby exoplanets to date.

Astronomers have discovered an additional 100 new worlds in data collected by NASA's exoplanet-hunting spacecraft TESS, ...

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial objects less random.

Talk about a hot mess. Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees Fahrenheit — hot enough to melt rock into a churning ocean of magma and ...

The molten planet, with an atmosphere rich in sulfur-bearing gases, is unlike anything astronomers have ever smelled.

Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly ...
